Thats cool but where question
Sean bought a laptop and a printer. He sold both items for £1,500 getting £1,300 just for the laptop. Sean made a 46% profit on the cost of the printer. What was the cost of the printer? Give your answer to 2 decimal places.
Answer: £137
Step-by-step explanation:
Since Sean sold both items for £1,500 getting £1,300 just for the laptop, the slave price of the printer will be:
= £1500 - £1300
= £200
Since we are informed that Sean made a 46% profit on the cost of the printer, the cost of the printer goes thus:
= £200 /(1 + Profit percent)
= £200 / (1 + 46%)
= £200 / 1.46
= £136.99
= £137 approximately
What method of solving a quadratic equation is shown here? A set of expressions shows the solution of the quadratic equation shown on line 1. Line 2 shows an equivalent expression of two factors. Line 3 show two separate equations with each factor set equal to zero. Line four show two solutions for the value of x. A. Quadratic formula B. Factoring C. Grouping
Answer:
Factoring
Step-by-step explanation:
When we are solving a quadratic equation by the factorization method, each factor is set as being equal to zero.
The solution of each bracket of factors gives the root of the quadratic equation.
For example;
x2 + 16 = 10x
We now have;
x2 - 10x + 16 = 0
x2 - 8x - 2x + 16 = 0
x(x - 8) -2(x - 8) = 0
(x-2) (x-8) = 0
(x-2) = 0
Then x = 2
Or
(x-8) = 0
x = 8
Hence;
x = 2 or x= 8
Give the quotient in simplest form:
Answer:
x
Step-by-step explanation:
x/y / 1/y =
x / 1 x y / y =
x / 1 x 1 =
x

BC has endpoints at B(3, 8) and C(7,6). Find the midpoint M of BC.
Write the coordinates as decimals or integers.
Submit
Answer: (5, 7)
Step-by-step explanation: Midpoint formula is ((x1 + x2)/2, (y1+y2)/2) where (x1, y1) and (x2, y2) are points on a line. Thus
(3+7/2, 8+6/2) = (5, 7)
In a race , Ram covers 5 km in 20 min. How much distance will he cover in 100 min ? This is for (348919) ;-; I hope I was not mean if so am sorry but is for ( 348919)
Answer:
25 km
Step-by-step explanation:
Distance covered in 20 min = 5 km
Distance covered in 1 min = 5/20 km or 1/4 km.
Distance covered in 100 min =
1/4 km x 100 = 25 km

Hello There!
First thing we notice is that the y intercept is at (3,0) meaning that they have some sort of fee that has a charge of 3 dollars (represented by the 3)
Because the fee is 3 dollars we can immediately eliminate answers B and C
Now we want to find the charge for each bag of Potpourri (this can be represented by the slope)
Once again we want to choose two points on the line and plug it in into the slope formula
the points are optional but i have chosen the points (1,4.5) and (2,6)
*plug it into the slope formula*
[tex]slope=\frac{6-4.5}{2-1} \\6-4.5=1.5\\2-1=1\\slope =\frac{1.5}{1} or1.5[/tex]
so we can conclude that the charge per bag of potpourri is $1.50 leading us to answer choice A
h−6 ≤−8.4
hope you have a good day stay safe
Answer:
h ≤ -12/5
Step-by-step explanation:
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "8.4" was replaced by "(84/10)".
Rearrange:
Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :
h-6-(-(84/10))≤0

Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a fraction from a whole
Rewrite the whole as a fraction using 5 as the denominator :
h - 6 (h - 6) • 5
h - 6 = ————— = ———————————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
(h-6) • 5 - (-42) 5h + 12

h + 2.400 ≤ 0
The value of h is less than or equal to -2.4.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
h−6 ≤−8.4
Now, add both side 6
h−6 + 6 ≤−8.4 + 6
h ≤−2.4
Hence, the value of h is less than or equal to -2.4

1478 cubic feet
First, calculate volume of the shed, then minus that by the volume of the cubes...
Volume(shed) = 12*12*12 = 1728
Volume(cube) = 2.5*2.5*2.5 = 15.625
1728 - 15.625(16) = 1478 cubic feet

For the function, find the points on the graph at which the tangent line is horizontal. If none exist, state that fact. SHOW WORK PLEASE!
9514 1404 393
Answer:
A. (-√2, 3+(4√2)/3), (√2, 3-(4√2)/3)
Step-by-step explanation:
The tangents are horizontal where the derivative is zero. The derivative of the given function is ...
y' = x² -2
This is zero when ...
0 = x² -2
2 = x²
±√2 = x . . . . x-values where the derivative is zero
__
The corresponding y-values are ...
y = (1/3x² -2)x +3
y = (1/3(2) -2)(±√2) +3 = 3 ∓ (4√2)/3
The turning points are (-√2, 3+(4√2)/3) and (√2, 3-(4√2)/3).

Last Option [tex] {y}^{6} \div {y}^{2} [/tex]Step-by-step explanation:
This is because,
As,
[tex] {a}^{x} \div {a}^{y} = {a}^{x - y} [/tex]
Here ,
[tex] {y}^{6} \div {y}^{2} [/tex]
[tex] = {y}^{6 - 2} [/tex]
[tex] = {y}^{4} [/tex]
And here the result does not simplify to,
[tex] {y}^{3} [/tex]
Hence, Last Option is the correct answer
